Mounting structure for a packing ring seal segment in a turbine |
摘要 |
A packing ring holder assembly for packing seal segments about a steam turbine rotor includes a nozzle box and a holder cooperable to form a dovetail for securing packing ring segments to the nozzle box. A spring is interposed between the nozzle box and packing ring segment to bias the latter radially inwardly for sealing with the rotor. The holder includes a shoulder for preventing axial movement of the spring in one direction.
